....CAC scheme presented in Section 5. Section 6 applies the CAC scheme to an illustrative example and evaluates the performance of the proposed scheme vis a vis two related approaches. Finally, Section 7 gives some concluding remarks. 2 ATM Network Communication The asynchronous transfer mode (ATM) [1, 5, 9, 11, 25] of high speed communication is a technique of transporting, multiplexing, and switching fixed sized data units called cells using special hardware called ATM switches [28] The following are the major characteristics of communication in ATM networks: ffl connection oriented data transmission, ....

....real time video, etc. and have the scalability to work over wide areas and handle high bandwidth applications. These characteristics are the consequence of the use of relatively small data units, fast hardware switching, and a protocol architecture that includes an ATM adaptation layer (AAL) [1, 5, 9, 11, 25] that provides appropriate interfaces for different service requirements. 3 Related Work In this section, we briefly discuss some notable proposals related to the current work. These include other models that capture traffic correlation, other traffic control schemes that can handle correlated ....

....significantly the jitter for delay sensitive services such as voice and video. In addition it leads to considerable simplification in hardware processing and in buffer and queue management. Hence minimal functionality is required in the switching nodes thus facilitating switching with low delays [15]. Asynchronous multiplexing of cells belonging to different sources permits flexible allocation of bandwidth, unlike Synchronous Transfer Mode (STM) where bandwidth is allocated only in integer multiples of a chosen rate. In ATM based networks statistical sharing between sources facilitates ....

The ATM cell A fiber optic link has a much higher transmission speed. For example, in SONET SDH [7], the line rate is a multiple of 51.84 Mbit s, for the so called OC 1 level in SONET, which corresponds to a multiple of 155.52 Mbit s for STM 1 level in SDH. Common multiples for STM levels are 1, 4, 8 and 16. For example the STM 4 level has a line rate of 622.08 Mbit s. Furthermore, optical ....

Today, new multi Gbit s optical integrated networks, which carry simultaneously diverse real time synchronous traffic, intra system traffic with stringent latency requirements, and intersystem traffic, are under development [BCF 92] [Che92], Gre92] KBH 92] Kun92] Tol92] However, while the Wavelength Division Multiplexing (WDM) technique has further manifoldly increased the transmission capacity on optical fiber [Bra90] the performance increase of supporting nodal electronics and (software) processing needed for switching, ....
